What is the best ROM for battery life? - Redmi K20 / Xiaomi Mi 9T Questions & Answers

I'm already on pixel experience 11 for a few days but the battery drain is increased now compared to the global MIUI. Is there a better ROM or should I revert back to MIUI?

Lineage, but it depends on apps you have, modules turned on,.etc.

Yeah Im currently on pixel experience 11 and I kinda feel that battery drain is worse than MIUI however it lasts 5 hours SOT and it's buttery smooth. Idk what to do

Stable ROM do you use?

I'm facing issues with the standby time of the stock OOS 3.5.6. I want to try other ROM which can fix it. I want a ROM with nice battery/performance.
Which ROM should I try?
Thanks
I'm currently using Cosmic OS it's pretty good, everything runs smoothly and the developer support is great!

I have been using cypher os since early dec last year, and it has been very good. SOT for me isnt as good as CM13.1 (8:30h SOT vs 7:30h SOT on cypher, but standby time is great if you use greenify with aggressive doze. I get around 2-3% overnight drain sometimes more if i leave wifi on.
Hmm, I'm gonna try it.
The main reason I'm looking for a ROM is because the battery drain overnight. I use two SIM cards, and the "phone idle" is higher than expected. I use stock ROM, OOS 3.5.6
Resurrection remix is good.

ROM for good battery life?

Hey! I am currently running 7.1.1 on my rooted OP5 but I am not satisfied with the battery life... is there any rom that sagnifically improves the battery life of the oneplus 5?
You can try RR unofficial with Blu Spark Kernel. It has an fully working OOS Stock Cam and comes with YouTube Adaway and background player. Also i get 9 hours SOT with the default kernel profile and no heavy multitasking. Or wait for an unreleased ROM, can't say the name yet, cause it's in an Testing Phase.:highfive:
What kind of battery life are you currently getting? Are you running stock OOS with the stock kernel? Switching to a custom ROM to improve battery life seems extreme if you haven't explored any options on your current ROM to improve battery life first. Are you trying to improve SOT? Reduce idle drain? Both?

Yeah, install EX kernel, significantly under-volt and under-frequency it, and install one of these super aggressive EX profiles that put half your cores to sleep. The delete all apps you don't use, particularly system apps, and Greenify everything else, turn off push notifications and location services, and turn down screen brightness to a minimum. While you are at it lock the phone in a volt to keep you from turning on the screen. You will get great battery life alright, but you may not like using the phone :banghead:
I'm running Pure Fusion with blu spark and am getting nearly 9hrs SOT
Great ROM and kernel combo imo

which is sthe smoothest rom for battery life?

Hi, I didn't find a Q/A thread so I ask here.
I came from a rn4. I loved to use Los ext, it was one of the best rom for battery life. Now I am with miui 11 stock and debloated (I removed almost all ****), but still I m having a battery drain. In fact tonight it used 5% of battery in less than 8 hours with wifi and screen rotation only. I think it's too much!!
I red that some people can last their android battery up to 3 days with 4 hours sot, and I was stupified.
So which is the best rom at the moment for rn7, looking at: stability, smoothness, battery life, gaming, customization?
Does Mi app like themes, fonts, etc are removed normally in roms, and if yes, do developer create their own menu in setting for these things?
Who is using the Rom that will suggest me, which SOT you get and how much battery drain do you have in 8hours sleeping time with wifi only?
Thank you a lot! ?
When system running ok i got always the same sot on each rom i tested.
Stock Global, xiaomi.eu 10 and 11, pixelex 9+ and LOS16.
in each rom i mostly get 2 days with 6-7 h SOT.
battery drain over night in flight mode only 1-2%.
no big differences in the Roms for me.

That is still way too much for such a big battery ESPECIALLY in Airplane mode. It should NOT drain a single % of battery during more than 12h of idle, where as right now it can hit up to 10% for me, which is just unacceptable
For me, my phone doesn't lose any single percent of battery in 12h, in airplane mode

There are actually massive differences... IMHO one of the best ROM's is not even on XDA. https://os.revtechs.me
after a new install of LOS 16......
last 2 nights in airplane mode i didnt lost any percent.
first complete akku charce i got easyly 8h+ SOT
maybe old install was faulty....

HI, are you using some of them? How much sot?
It seems that rooting and using Roms on this phone is pretty useless on the battery side, because nobody talks about 9-11 hours of sot using roms.

Rooting is absolutely no problem and who ever presumes having 9-11 SOT is simply hallucinating... 7-8h is realistic... I don't even want to imagine how sad individual lives are being staring at a phone 8h out of a 24h day...

A good stable rom for battery backup?

Hi all
I thought I'd ask the experts about what are in your opinion some good roms for battery backup?
I'm currently on stock MIUI Global 11.0.5.0 (PFGMIXM) but I'm not much satisfied with the battery backup (5-6hours SOT).
I need some stable firmware since I use my phone mostly for work, no gaming, no social media, just phone calls, messaging and some light youtube usage.
Thanks!
Ion OS is brilliant, especially for battery - sourceforge.net/projects/i-o-n/files/device/xiaomi/lavender/ Around 10-11 hours SOT.
Anyone can compare MIUI vs Xiaomi.eu VS Pixel?

Miui right now just being laggy and jerky sometimes with animation, thus pixel based cutom rom just some having like miui and some is dont. I prefer evolution x on latest build, which smooth operation per my multitasking usage(on stock kernel obviously), whilst the battery just doing better other than resurection remix, pixel experience etc.

Could you be more specific about how long the battery lasts, I mean that if you are using your phone for like 4-5 days then 5-6h of SOT is quite normal for this phone but if you meant just one day then it should be about 10-11h of SOT as there will be less energy consumed by things like cellural network.
I had pretty good battery backup with POSP by AmulayaX but i found out that slow-motion isn't working so i switched to StagOS (unofficial EAS by Jimgsey) and i like this rom but i have some small issues and i consider switching to official.

5-6h SOT in 2 days. I'm not playing games I only use my phone for calls, whatsapp, emails and web navigation.
I'm on dual sim though.
I could never achieve 10h SOT in stock. Any hints for some good rom that can do that?
Thanks

Someone already suggested you to try Ion Official for Redmi Note 7 as it is EAS & feature rich also. But for more you can try Bliss ROM as well. Last but not the least LineageOS 17.1 Official. I'm currently using Bliss ROM. It is the best in all others upto now i have tried.

U can't reach 10 h SOT by 2 days on battery.
Calculate 0,5 %/h idle drain
2 days 48h - 5 hours Active drain = 43 h idle time
43 x 0,5 = 21,5 %
so round about 20% battery is lost in idle time
so 80 % for active drain.
Charging battery at 15%
80-15 = 60% left for active drain
On mostly all roms i tested i get an active drain by 10% per hour
Wud be for u 6 hours SOT
Seems normal drain with ur MIUI
But aosp roms are so much faster and mutitasking so much better compared to MIUI.
I only got 3 GB model and there no way back to MIUI
I gave PixelE+ a try but I'm experiencing less battery backup than stock (and some random freezes too).
I'll try ION or Xiaomi.eu in the coming days.
Meanwhile what about changing kernel? Any good recommendations please?

for me changing kernel isnt a game changer
its all about SOT, screen brightness for sure and good working deep sleep.
Screen is biggest power consumer.
Kernel maybe change covernor and undervolt cpu. sure this brings a lil power. but trust me it makes just a very lil differece. u cant compare ur drain because ur usage isnt same.
if wanna judge a kernels power consumtion u have to do all the same.
watching 2 hours youtube, play same game aso with same screen brightness with same wifi state aso.
i bet theres no "big" difference.

I'm currently on Pixel and I can make 4h SOT in 2 days. I don't play games or use YouTube. Just phone calls, whatsapp, browser, emails and I'm always on dual sim.
With stock MIUI I used to reach 5-6h SOT in 2 days so with my personal usage Pixel is worse in battery life compared to stock MIUI.
I'm thinking of trying something like Xiaomi.EU now since it's based on MIUI stock...
As i say, for me there are just few differences in battery life from rom to rom.
Miui is slow and bloated compared to non miui based custom rom.
When u just installed new rom u have more drain cause of trying out the rom. U have more usage compared to ur old rom. Lets get rom settle for a while before judge.
At least all rom take power. All rom need display. I think display always takes same power in every rom when u got same brightness.
At home in ur wlan mostly watching YouTube u get better battery (maybe under 8% per hour drain maybe less) than navigating in the sun with mobile data (cost 12% per hourand more) battery

I'm with you however I'm currently on Xiaomi.eu 11 (debloated) and battery backup is much better than Pixel. I hit 6h SOT on the first run, expected to improve in the coming days after a few charging cycles.
Same usage, the exact same apps running.

Best battery life custom rom for Mi9T/K20

I have used Arrow OS, Pixel Experience, Havoc OS, Evolution X and LOS but I haven't had luck with battery life. Every rom had massive idle battery drain or missing features (LOS) which stopped me from using these roms. What's the best battery friendly rom for K20?
Maybe the problema is of your battery and not the rom

My problem is that I get about 3 days on full charge on miui 12.5 but only like 1.5 days on any custom rom. I use my phone about 3-3.5h a day and I'll be happy if I could find rom that at least give me 2 days of battery life.
